My lnventionrelates generally. to printing machineryand more particularly to a machine designed for coloring embossed plates, such as for instance, motor vehicle license plates, embossed advertising plates or any metal or composition plate which is embossed to form raised letters, numbers'or the same in length and diameter and the characters, and the surfaces ofwhich raised portions are distinctively colored with re spect to the back ground or depressed portions. I i

It will be understood that embossed vehicle license plates and advertising. plates are generally coated with a suitable liquid enamel or vitrifiable substance and after the same has been applied it is necessary to bake the coated plates in order to'cause the enamel or vitrifiablesubstance to become hardened and set on theplates.

My improved machine is particularly designed for receiving embossed plates after the same have been'coated so as to, color the back ground and applyto the surfaces Specification of Letters Patent.

of the raised or embossed portions of said plates a liquid enamel or vitrifiable substance which is distinctive in color with respect to the color of the back ground, said machine being constructed so as to' very rapidly perform its functions and operations and to evenly distribute the enamel or vitrifiable substance over the surfaces of the raised letters or characters.

A further object of my invention is to provide an embossed. plate printing machine which is comparatively simple, can be operated with little power and which can be readily adjusted so as to accommodate plates of varying widths.

W'ith the toregoingand other objects in view, my invention consists in certain novel features of construction and arrangement ofparts, hereinafter more fully described and claimed. 7 Referring bynumerals to the accompanying drawings, 10 designates a suitable support on which is positioned a pair of upright parallel'plates 11 framed together in any suitable manner and arranged between the upper portions of said plates at one end is a feeding table 12 and at the opposite end a discharge or receiving table 13.

Formed in the upper portions of the plates 11 are rectangular notches 14 and tween every other pair of these notchesare blocks 15in the upper portions of which are formed notches 16. Arran ed for ro- ,tation in suitable bearings formed in the plates 11 and below the notches 1 1 1s a horishafts 17 are located so that the peripheries of said rollers are substantially inhorizontal alinement with the tops of the tables 12 and 13, and thus the plates which are fed from table 12 are carried over by the rollers 18 through the machine and delivered onto table 13..

@omparativelyshort rollers 19 are located on the shafts 17, said rollers being provided with setscrews 20,wherebythey may be adjusted on said shafts toward and away from the rollers 18, and formed womb of said rollers 19 is a rib or flange 21-. By making the rollers 19adjustable with respect to the carrying rollers 18, plates of different .85 "projecting upwardly from said plates bewidthscan be accommodated in the machine, it being understood that sa1d rollers are adjusted so that the edges of the plate engage the ribs 2i and thus the latter serve all of the sprocket wheels 22 and beneath the sprocket wheel 25, and thus as shaft 24 is rotated, corresponding rotary movement is simultaneously imparted to all of the shafts 17 upon which the carrying rollers 18 aremounted.

Fixed on the end of shaft 24 on the side with the pinions 23 is a pulley 27 which is adapted to receive adriving belt (not shown). 'Positioned in the notches 14 are journal boxes 28, the same being provided with horizontal extensions 29 which overlie adjacent portions of the plates 11 and screwseated in'these projections 29 are adjacent screws 30, the lower ends of which bear against the upper edges of said plates '11. The shanks of bolts '31 pass through suitable openings formed in the extensions 29. and'the threaded portions of said'bolts are screw-seated in theplates 11. The construction just described provides means for vertically adjusting the journal boxes 28 and locking the same intheir adj ustedjpo sitions.

Mounted for rotation in the corresponding pairs of journal boxes 28 are shafts 32,

*the'samebeing paired with and arranged directly above the shafts 17 and carried by the central portions of these shafts are ink applying or printing rollers33, the; same being preferably formed of rubber or,

analogous material.

. Adjustably mounted on the shafts 32 are rollers 34- provided with hearing ribs 35 and which latter are intended to engage the.

edges of the plates during their passage through the machine and hold said plates in proper position with respect'to the flexible orelastic'inking rollers. (See Fig. 2.)

Fixed onthe ends of the shafts 32 are pinions- 36 which are paired and mesh with the pinions 23 and thus the plate'carrying rollers 18 and corresponding inking rollers 33 are simultaneously driven toward each other and at the same rate of speed. I

' Loosely mounted in the notches 16 are the non-circular ends of shafts 37 in the central portions of which are formed intersecting right and left hand threads 38. Loosely mountedon each shaft 37 is an ink distributing roller 39, the same being pro vided with a pin or screw 40, the inner. end of which engages in the corresponding grooves 38.' V 7 It will be understood that the shafts 37 are held against rotation and that the rollers 39 rotate upon said shafts by reason of their frictional engagement with the inking "rollers 33, and during the rotary movement of said rollers 39 they will reciprocate lengthwise upon the shafts 37 by the engagement of the pins 40 in the intersecting grooves 38. This movement insures an equal.

distribution of the ink or vitrifiable substance upon the rollers 33 and which rollers apply said ink or vitrifiable substance directly to the surfaces of the raised portions of the plates.

Projecting upwardly from the plates 11 is a' suitable framework 41 and adjustably positioned thereupon is one or more con tainers 42 for the ink or vitrifiable material, 7

the 331118 being discharged onto the ink rollers through valves l3 which are located in the lower ends of'said containers.

Located on the innerend of the feeding table 12 are guides 44, the same being transversely movable so that they may be ad justed to various widths of plates.

In the operation of my improvedmachine rotary motion is imparted to shaft 24: and

by reason of the various driving connections corresponding rotary motion is imparted to V thecarrying rollers, inking or printingrollers 33, and ink distributing rollers 39. The ink from containers 42 is delivered onto the rollers 33 and as the machine is operated this ink is evenly distributed over the surfaces of said rollers by the rollers 39. The

rollers 19 and 34 and guides 44 are adjusted to the width of the plates to be passed through the machine and said plates are now fed from table 11- between the first pair of carrying and inking rollers. This first pair of rollers will frictionallyengage the plate and draw the same'into the machine and said plate will be successively engagedby the various pairs of rollers and will finally discharge onto table 13; V

During'the passage of the plate through the machinethe surfaces of the raised portions will be coated with ink, which it will be understood is a suitable liquid enamel or vitrifiable material, and when said plate is delivered onto table 13,.it is in condition to be placed in the drying room or oven.

A machine of my improved construction is comparativelysimple, requires practically no attention after being properly adjusted, and can be operated at comparatively high speed, and therefore, will very rapidlyperform the work required.

It Will be readilyunderstood that minor changes in the size, form and construction ofthe various parts of my improved macolor applying rollers.
